The other day I was talking to a guy at the auto parts store and he asked me if I noticed any mileage difference with the visor that is on my truck. I told him it was there when I bought the truck, so no. He was telling me about his and a buddys truck. Both are inentical Toyota trucks except his buddys is extended cab and his has a visor. He said that his buddy gets about 5-6 mpg more than he does and he was wondering if it was the visor. His visor was on his truck when he got his, too. I know that there are a lot of factors that could make that mileage difference like driving habits, state of tune, etc. It got me to thinking about the visor on my truck though. I was wondering if anyone here has any actual experience with the visor to no visor mileage difference? I don't want to remove mine if it won't make a noticeable difference.
